The Jeddah Corniche Circuit is a 6.175 km motor racing circuit built in the Red Sea port city of Jeddah, in Saudi Arabia. The circuit staged the inaugural Saudi Arabian Grand Prix on 5 December 2021 as the penultimate race on the 2021 Formula One season calendar. Named as the 'fastest street track' on the Formula One calendar with Formula One cars simulated to have average speeds in excess of 250 km/h (160 mph), the track is the second-longest track on the Formula One calendar, with only Spa-Francorchamps being longer. Additionally, three consecutive sections of the circuit have been marked out as potential DRS zones. The circuit is located on the Jeddah Corniche adjoining the Red Sea. The circuit was designed by Carsten Tilke, son of the famed circuit designer, Hermann Tilke.
